the steering worked fine, it's just a servo doing servo stuff, however the ESC takes a bit of experimentation; a normal servo takes commands ranging from 0 to 180 corresponding to the relevant angle, which would imply that for the ESC 90 would be stop, 0 maximum reverse and 180 maximum forwards, however i found that at 90 the car would start reversing and at about 99 the car would go forwards. just something to look out for.
